Rilevamento dell'hardware
Dispositivi connessi
Per verificare il corretto rilevamento dell'hardware del portatile, è sufficiente aprire un terminale e digitare il seguente comando:
lspci
Il comando restituirà una schermata simile alla seguente:

CPU policy governors:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
userspace conservative ondemand powersave performance
Predefinita: ondemand
Qualche accorgimento:
sudo apt-get remove powernowd
sudo apt-get install cpufrequtils sysfsutils
Semplice trick per utenti Gnome:
sudo dpkg-reconfigure gnome-applet
Rispondete YES alla domanda che verrà fatta e potrete modificare frequenza e profilo della CPU con un semplice click sulla applet CPU Frequency Scaling Monitor presente nel vostro pannello di Gnome.
Controlliamo che sia tutto OK:

Considerazioni
AIGLX e Compiz/Beryl perfettamente funzionanti con i driver OPEN;
TV OUTPUT e DUAL MONITOR funzionanti solo in modalità CLONE con i driver OPEN;
Per abilitare Xinerama sono necessari i driver PROPRIETARI (fglrx) con conseguente impossibilità di utilizzare AIGLX;
Per conservare gli "effetti desktop" (Compiz/Beryl) con il DUAL MONITOR è necessario installare XGL (non sempre funzionante).
